Title: Method and apparatus for detecting boiling of liquid
Inventor: SUMIDA JUNJI
IPC: A47J27/21
Filed: 1986-02-21
Abstract: PURPOSE:To detect the boiling of liquid accurately, by converting vibration generated by a rise in the temperature of the liquid into an electrical signal to detect a displacement point at which the voltage corresponding to the signal changes to a low level from a higher level than a reference voltage corresponding to the boiling of the liquid. CONSTITUTION:A detector is made up of a vibration sensor 3,a reference voltage setting means 5, a discriminator 6 and the like. An electric heater 2 is mounted at a lower part of the side wall of a container 1 while the sensor 3 is placed on the bottom thereof. For example, water W is put into the container 1 and while the water is being heated, a vibration generated by a rise in the temperature is converted into an electrical signal with the sensor 3 and detected through an amplifier 4. On the other hand, any voltage between the output voltage at which a liquid reaches the boiling point and the output voltage at which a balance level is reached is set as a reference voltage V0 by the means 5 beforehand. The discriminator 6 is used to detect the displacement point at which the voltage corresponding to the vibration level detected by the sensor 3 changes to a lower level from a higher level than the reference voltage V0 to detect the complete boiling.

IPC: H02P27/06
Filed: 1994-03-09
Abstract: PURPOSE:To eliminate the need for a transformer for detecting induction voltage and to prevent the rotating speed when detecting free-run state from being reduced by controlling the output current of an inverter based on a current command signal which decreases to a preset value after a certain amount of time since an induction motor turns into a free-run state and a deviation signal. CONSTITUTION:When a current command signal is output from a pulse current command means 7 so that it decreases to a preset value after a certain amount of time when an induction motor 5 becomes a free-run state, the output current of an inverter part 4 is controlled based on the deviation signal between the current command signal of the command means 7 and the detection signal of a current detector 6 by current control parts 29 and 30. At this time, the ripple component of the current control parts 29 and 30 is extracted while nearly no deceleration torque is generated at the induction motor 5 and the rotary state of the induction motor 5 in free-run state is obtained by a rotary state detection part 32.

Title: Method for reproducing magnetooptic information
Inventor: YAMAMOTO MASAKUNI
IPC: G11B11/105
Filed: 1985-02-28
Abstract: PURPOSE:To eliminate the effect due to fluctuation of the distance between a recording and the detection system by splitting a luminous flux into the 1st luminous flux comprising a polarized component in a prescribed direction and the 2nd luminous flux comporising the polarized component in a direction vertical to the prescribed direction and interferring the 1st and 2nd luminous fluxes to detect information. CONSTITUTION:Light irradiated from a light source 61 is collimated by a collimator lens 62, becomes a luminous flux 20 subject to linear polarization into P polized light through a polizer 3, condensed on an optomagnetic disc 24 and reflected. In this case, the polarized azimuth of the reflected light is rotated to produce an S polarized component, which is reflected by a polarized beam splitter 22, bent by a mirror 27 and becomes a luminous flux 25 without almost any loss of luminous amount. On the other hand, the P polarized light component component transmits through the polarized beam splitter 22, is reflected by the beam splitter 2 and becomes a luminous flux 26. The luminous fluxes 25, 26 are interferred by a beam splitter 30 and propagate in two directions and are condensed on photodetectors 33, 34 by condenser lenses 31, 32 respectively and detected. Thus, the adverse effect due to the change in the distance between the recording medium and the detection system is eliminated.
